BUCKLE..

SPECIFICATION forming p.rt of Letters Patent N0. 460,721, dated. October 6, 1891.

Application filed August SO, 1890. Serial N0. 363,517. (N0 mode1.)

T0 all whom it may concern:

Be it known that I, JONAS PARKER, a citizen of the United States, residing ab \/Villia msuseful Improvements in Buckles; and I here'= by dec1are the following t'o be a fu11, olear, and

exaet description of the Same, referenee being had to the aocompanying drawings, wherein Figure 1 is a front elevation of a buokle embodying my invention, together With portions of a suspender-web, tabs,and a tab-ring, illustrating one manner in which the buckle may be used. Fig. 2 is a detaohed view 0f he buckle spread open. Fig. 3 is a seotion of the buckle olosed together with the tab-ring and tabs on the line w m 0f Fig. i. Fig. 4 is a p1an view of a, blank for forming the cross-bar, und Fig. 5 is a detaohed perspective view of the cross-bar. v

Like symbols refer to Iike they occur.

My present invention relates, generally, 130

the construetion of that dass of buckles com- 2 5 monly termed suspender-buckles, but is more especially intended as an improvement ou the dass of clanup-buckles having a double pivoted clamping-bar 01 clamping-plate. fo1 whioh Letters Patent N0. 417,582, dated December 17, 1889, and N0. 426,678, dated April 29, 1890, were granted to me.

The first objeot I have in view is to utilize the bottom 01 lower bar 0f the buckle-franne as a keeper f01 the hab-fing and a guard for the nose 0f the buckle-hook, and to this end parts wherever I form the lower bar of the buok1e with par-' alle1 dependent folds, whieh form projections which exteud down toward the nose 0f the hook und b( tween which the shank of the hook Tests, and I oonnect said dependent keepers by a cross-bar below the lower fmmebar, with which eross-bar the shank of the hook engages, and a buokle-frame having such a conscruetion en1bodies the fi1st feature of my invention.

The second object I have in view is to -increase the strength and rigidity of the slotted elamping-plate, and 110 this end I form a rib or flange thereon parallel with the slot by turning at righb ang1es to the clamping-plate a porti0n of the metal from the slot, und a clamping-bar having such construction embodies a second feature of my invention.

The third object I have in view is to simplify und strengthen the r-a-ised cross-ba'r Whichcoaets with the olanuping-plate to fornu the olamping devioes, and to'this end I stamp or out said oross-bav from sheer metal of 'greater Width at ehe middle than ab the ends and bend up the edges thereof ab t he wider portion of the blank, and a raised cross-bar having such a consrruction embodies the third feature 0f my invention.

There are other minof features of invention, all as Will hereinafter more fully appear.

I will now proceed to desoribe myinvention more fn11y, so that othe'rs skilled in oho a1t 10 whieh il: appertains may app1y the same.

In the drawings, A indicates the Web 0f a suspender; B B, the usua1 suspender-tabs o1 an. equivalent strap; C, the tab-ring, and D a buckle embodying che features of my present invention. Saidbuekle D has the frame lof wire or other suitable material, f0r the support of the cross-bar o1 cross-bars 2 2, -and on the upper bar l" of said fr'ame is pivoted the s1otted clamping-plate 3, the buokle-hook 4 being in turn pivoted 011 the free edge of the slotted clamping-plate.

The upperbar l und the side bars l of the frame may be of any des ired form; but the lower bar l thereof I form with two dependent folds or keepers e e, oonnected by the locking-barf and plaoed ab about the center of the buckle 01 at a.point corresponding to the position of the buokle-hook 4 when tl1e buckle is c1osed. The hook 4, when the buokle is olosedor clzunping the web A, passes under the 10we1 bar 1 of the frame, (see Figs. 1 and 2,) and the nose of the hook is turned backward, so as t0 rest against and be oovered by the web A.

In the present; ease I forrn the locking depression 01' recess 4, which receives the 100king-barf, in the back of the shank of the hook the nose of the hook 4, (see Fig. 3,) so that when tl1e buekle is closed its shank will rest between tl1e folds er keepers e ewith its nose t0 the real, and the folds 01 keepers will extend down, so as to obstruet the space between the swell at ehe back 0f depression er reeess 4 anal the nose of ehe 1100k, and thus prevent the escape of the tab-1fing C, as well as gua1d the nose 0f tl1e hook 4:.

In cutting away the metal from the clarnping-plate 3 t0 forn1 the slots 3 thereof I leave a projecting tongue 0f metal on one 01' both edges of the s1ot, as indicatecl by ehe clotted lines, Fig. 52, ancl saicl tongue I tu1n up ab right an gles to tl1e under face of ehe elamping-plate 3 10 forn1 the flanges 01 1ibs 3", which n0t only bite 011 the Web A when the buckle is closed, but also serve t0 inerease the strength and rigidity of the clamping-plates.

2 2 indicate the cross-bars having the raised faces 2, adapted t0 enter tl1e slots 3 of the clamping*plate 3. These cross-bars I preferably form by first striking 0ut sl1eet-rnetal blanks, such as shown in Fig. 4 of the drawings, ancl then bencling 01 folding the same, as indicatecl by tl1e dotted line, to px0duce tl1e cross-bm, substantially as shown in Fig. 5, haVing the raisecl faces 2 anal the tapering ends 2", 'adapted 150 be coiled 01 bent around the side bars 1 0f the bnckleframe 1.

The specified construetion of slotted damping plate anal bed-ba1 aclds materially 130 the stre'ngth and lightness of buekle, recl uces Ehe c0st of manufaetnre, anal adds to the efl1eiency of the clamping action of the eross-bar and clamping-plate.

The buckle, being of substantially the coustruetion hereinbefore speeified,is appliedto the web by firso ope nlng 0ut the buekle, as shoWn in Fig. 2, then passing the web A under the upper frame-bar l", ben over the clamping-bars 2 and under the lower bar l, after whicl1 the elamping-plate 3 is bronght down 011 web A, as shown in Fig. 1, and the bnckle-hook 4 passed uncler the lower bar 1 and its loeking recess 01 depression 4" caused to engage bar f to the back and between the downwardly-projecting folds o1 keepers e e and prevent the escape 0f t-he t-ab-ring C.

Having thns deseribed my invenrion, what I claim, and desire to seenre by Letters Patent, is-

1. In a bnekle, the combination, With the buckle frame having dependent folds 01 keepers e e ancl loeking-barf, wl1icl1 connects said folds, 0f a hook having; a locking-depres sion a little distance above the nose 0f the hook in the sl1ank thereof, snbstantially as an(l for the purposes described.

2. In a buckle lmving a frame and raised cross-bar, a clamping-plate having slots f0r the reeeption of 'the mised cross-bar, said sl0ts provided with flanges 3 a1; tl1e edge of the slots and ab substan'tially 1ight angles t0 the nnder faee 0f the clalnping-plate, substantially as and. f01 tl1e pmposes specified.

In a suspender-lmekle, the combination, with a continuons buckle-frame having tw0 parallel and rigidly projecting pendants, whieh project fr0xn the bottom bar 0f tl1e frame ancl are connected above by a trans- Verse bar, with which the shank 0f the h00k engages, 0f a pivoted hook having a shank arranged and adapted to engage the transverse bar be'hveen tl1e parallel pendants, 1;he nose of said hook being contiguons 1;0 and intermecliate of the free ends 015 seid pendants when the parts are in osition, substantially a-s 'and for the purposes specified.

In tesimony Whereof I aflix rhy signature, in presence of two witnesses, this 27th day of August, 1890.

JONAS PARKER.
